Got error “Unhandled Exception: Bad state: No element…” when call “cameras.first” run on iOS Simulator

Reason

iOS Simulator CANNOT use Camera

Reference

flutter – availableCameras is empty in IOS but no problem in Android – Stack Overflow

The await expression can only be used in an async function.

Wrong

void main() {
  final cameras = await availableCameras();
  runApp(MyApp());
}

Correct

Future<void> main() async {
  final cameras = await availableCameras();
  runApp(MyApp());
}
